I have Windows 10 installed on SSD(1) which is connected to sata port 1. I got a new SSD(2) and connected it to sata port 3. I disconnect SSD 1 from port 1 before installing Windows 10 on SSD 2. I got Windows all setup on SSD 2 and rebooted several times to make sure everything is fine. I then proceeded to reconnect SSD 1 on sata port 1. The computer boots SSD 1 and everything looks fine. When I go to Explorer I noticed SSD 2 is completely empty. Somehow the entire Windows installation on SSD 2 is being deleted by the first Windows installation. I have repeated this process three times and each time the same result. Why is Windows 10 deleting the Windows installation in another drive? This is just ridiculous.
